NOTICE
Timeout of simulation
10 minutes after changing (editing) a simulation parameter (the "Simulation value" parameter
is the exception), the simulation is automatically disabled and the device returns to normal
measuring mode. When a timeout occurs, the "Simulation mode" parameter switches to
"Disabled" and the error code "Cb" is no longer shown on the display. (Device status
conditions are also reset in PDM, AMS, FDT and FC375/475.)
9.3.4.1
Simulate constant pressure values
Procedure
To simulate a constant pressure value via remote operation (e.g. SIMATIC PDM), follow these
steps:
1. For the "Simulation mode" parameter, set the "Enabled" option to simulate a constant
pressure value.
2. Select the pressure value ("Process value") to be simulated from the drop-down list under
the "Simulation selection" parameter.
3. For the "Simulation value" parameter, set the desired constant pressure value for the
simulation.
4. Set status to be simulated for the "PV status" parameter.
5. Click "Transfer" to start the simulation.
6. For the "Simulation mode" parameter, set the "Disabled" option to stop the simulation.
Result
The measured value is replaced by a constant simulation value. The simulation influences the
output signal.
The diagnostic ID "Cb" is displayed on the device.
Note
The simulated pressure value has a direct effect on the configured process value (e.g. volume
or flow rate) and thus on the current output dependent on it.
